G'day Wegmann,

That's probably the best approach. Or have it in a configuration file for your utility somewhere I'd suggest. Unfortunately the MOM information within Portico is quite limited at the moment (doesn't implement the full MOM). However, if you need it in future, you can treat MOM data like regular Objects/Attributes/Interactions.

For example, if you wanted to be notified when a federate joins a federation, and get it's name and handle, you'd subscribe to the "FederateType" and "FederateHandle" attributes of the "ObjectRoot.Manager.Federate" class.

If you open up a default FOM, the MOM classes should be in there. If they're not, and the MOM is enabled on Portico, they will be automatically added. There is a RID file option to print the full FOM being used in the Portico log when you create a federation that you can use to verify that the MOM classes/interactions are there (they're all under Object/InteractionRoot.Manager).

Hope that provides some useful information!

Cheers,
Tim

Subject: MOM information or elsewhere?

Hi Tim,

I am writing a DIS-HLA gateway using Portico and our own DIS libraries. It is working well so far, but I am having trouble constructing my resulting DIS PDU header because I do not have the ExerciseID. The RPR FOM does not have this field, but I thought I read somewhere that it may already be in the MOM - hence the previous question. I was wondering if I could put it in the MOM. If so, how, and then how would I get to that information in the receiving gateway ambassador.

I realize this isn't exactly a Portico question, but I was posting to this group because I head that other people are using Portico with the RPR FOM.

Actually .. I think I just got it. If I give the Federation a name which is the exercise ID, ... I think that will solve it. Going to code and test.

Thanks!

All I really need to know is, in a Federate Ambassador, is it possible to extract information from the MOM? In the RTI.rid file, "portico.mom = enabled". Can I extract the fields and their values? If so, what are the fields and how do I get their values?

Thanks for the quick reply.

G'day wegmann,

I'm not sure what you're asking exactly. There is no way to link anything HLA directly to DIS via Portico. The RPR-FOM is similar to the DIS standard in that there is a lot of overlap between the two with regard to data and phrasing, but you cannot use it to directly interact an HLA federate with a running DIS simulation.

To achieve such a thing you'd need a DIS/HLA bridge (plenty floating around out there).

Is that what you're talking about? I'm not sure I fully understand what you're asking. Perhaps you could rephrase?

Cheers,
Tim

I am successfully using Portico with the RPR FOM to translate PDUs between DIS and HLA. I am needing to extract DIS header information in my federate ambassador. I have tried publishing and subscribing, and adding the information in my federate, but I am not yet successful in adding this information into the RTI.

Can anybody give me any ideas on how I go about extracting DIS header data, inserting it into the RTI (for selected PDU types) and extracting it in the Ambassador?

Thanks!

G'day Renan,

I don't know of any other related project for this or anyone to try it. I've got no Android background (sadly) so I have no idea how well it'll work, but I'd love to hear how you go!

Cheers,
Tim
